Communication partners are identified, quality of service is identified, user authentication and privacy are considered, and any constraints on data syntax are identified. Everything at this layer is application-specific.

This layer provides application services for file transfers, e-mailand other network software services. Telnet and FTP are applications that exist entirely in the application level.

Tiered application architectures are part of this layer. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a networkproviding freedom from compatibility problems.

Network Layer 3 Layer 3 provides switching and routing technologies, creating logical paths, known as virtual circuitsfor transmitting data from node to node.

Routing and forwarding are functions of this layer, as well as addressinginternetworkingerror handling, congestion control and packet sequencing. It furnishes transmission protocol knowledge and management and handles errors in the physical layer, flow control and frame synchronization.

The data link layer is divided into two sub layers: The MAC sub layer controls how a computer on the network gains access to the data and permission to transmit it.

The LLC layer controls frame synchronizationflow control and error checking. Physical Layer 1 OSI Model, Layer 1 conveys the bit stream - electrical impulse, light or radio signal — through the network at the electrical and mechanical level.

It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects. It was published in as standard ISO Tweet This Study Guide!
